“…Popularly known as the mangrove oyster, Crassostrea gasar is an estuarine species that occurs on the Brazilian coast from the State of Pará to Santa Catarina [23]. They are widely used for ecotoxicological studies, as they are filter-feeding organisms and have a sessile life habit and bioaccumulation capacity; this species has been used in several studies using biomarkers [24][25][26][27], demonstrating that they are excellent sentinel organisms to achieve the true characterization of environmental impacts on aquatic ecosystems.…”

The synthetic hormone 17α ethinyl estradiol (EE2) is a molecule widely used in female contraceptives and recognized as a contaminant of attention (Watch List) in the European Union due to its high consumption, endocrine effects and occurrence in aquatic environments. Its main source of introduction is domestic sewage where it can be associated with other contaminants such as microplastics (MPs). Due to their characteristics, they can combine with each other and exacerbate their isolated effects on biota. This study evaluated the combined effects of microplastics (MPs) and 17α ethinylestradiol (EE2) on two tropical estuarine invertebrate species: Crassostrea gasar and Ucides cordatus. Polyethylene particles were spiked with EE2 and organisms were exposed to three treatments, categorized into three groups: control group (C), virgin microplastics (MPs), and spiked microplastics with EE2 (MPEs). All treatments were evaluated after 3 and 7 days of exposure. Oysters exhibited changes in phase 2 enzymes and the antioxidant system, oxidative stress in the gills, and reduced lysosomal membrane stability after exposure to MPs and MPEs. Crabs exposed to MPs and MPEs after seven days showed changes in phase 1 enzymes in the gills and changes in phases 1 and 2 enzymes in the hepatopancreas, such as disturbed cellular health. The combined effects of microplastics and EE2 increased the toxicity experienced by organisms, which may trigger effects at higher levels of biological organization, leading to ecological disturbances in tropical coastal ecosystems.

“…Altas concentrações de metais (Pb, Zn, Cu, Cr e As) tem sido registradas nas águas e nos sedimentos de fundo e suspensos e na biota (Catharino et al, 2015;Guimarães & Sígolo, 2008;Gusso-Choueri et al, 2015;Mahiques et al, 2009). O conjunto de respostas observado nas ostras de Santos pode indicar contaminação por compostos orgânicos, principalmente em função da indução da atividade de DBF.…”

“…Apesar disso, a contaminação por estes poluentes persiste até hoje, sendo registradas altas concentrações de metais nas águas, nos sedimentos e na biota, provenientes de fontes antropogênicas (Catharino et al, 2015;Guimarães & Sígolo, 2008;Gusso-Choueri et al, 2015;Mahiques et al, 2009).…”

“…Além disso, apresentam também importância socioeconômica, uma vez que seu cultivo constitui uma fonte alternativa de renda para pescadores do litoral do Brasil (Carraro et al, 2012;CETESB, 2009). O mexilhão Perna perna e a ostra Crassostrea brasiliana são bivalves presentes no litoral brasileiro e tem sido extensivamente utilizados em estudos de biomonitoramento da contaminação ambiental (Catharino et al, 2015;Pereira et al, 2012;Seo et al, 2013) e mensurações subletais como as respostas bioquímicas (Abessa et al, 2005b;Francioni et al, 2007;Lüchmann et al, 2015;Maranho et al, 2012;Nogueira et al, 2015;Zanette et al, 2006) e a estabilidade da membrana lisossomal (Cheung et al, 1998;Song et al, 2007).…”
